DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise presented. The methods, devices, systems, and other features discussed below may be embodied in a number of different forms. Not all of the depicted components may be required, however, and some implementations may include additional, different, or fewer components from those expressly described in this disclosure. Variations in the arrangement and type of the components may be made without departing from the spirit or scope of the claims as set forth herein. Further, variations in the processes described, including the addition, deletion, or rearranging and order of logical operations, may be made without departing from the spirit or scope of the claims as set forth herein.

Embodiments of the present disclosure provide a technical solution that may be implemented, at least in part, on a computing device such as a communication device. The communication device may include well known computing systems, environments, and/or configurations suitable for implementing features of the method for knowledge base construction described herein such as, but are not limited to, digital broadcast devices, messaging devices, gaming consoles, medical devices, exercising equipment, personal digital assistants, smart phones, tablet computers, personal computers (PCs), server computers, handheld or laptop devices, multiprocessor systems, microprocessor-based systems, network PCs, server computers, minicomputers, mainframe computers, embedded systems, distributed computing environments that include any of the above systems or devices, and the like. According to the technical solution, a human face depicted in a digital image may be recognized, a personal identity of the person corresponding to the recognized human face may be determined, and a description of the contents of the digital image may be generated that accounts for the personal identity of the person.

FIG. 1 is a flow chart 100 describing a digital image processing method according to an exemplary embodiment. The digital image processing method may be implemented by a communication device.

At S11, a face corresponding to a person depicted in a digital image may be recognized.

For example, facial recognition methods based on detecting geometrical features on the face may be implemented at S11, facial recognition methods based on face templates may be implemented at S11, or facial recognition methods based on models may be employed. Among them, the template-based facial recognition methods may be classified into correlation matching-based methods, Eigenfaces methods, linear discriminant analysis methods, singular value decomposition methods, neural network methods, dynamic link matching methods and the like. For the model-based facial recognition methods include those based on Hidden Markov Model, Active Shape Model and Active Appearance Model.

At S12, identity information of the person corresponding to the recognized face is determined. The identity information includes at least one of an identification of the person corresponding to the recognized face and a relationship information describing a relationship between the person corresponding to the recognized face and a user. The user may be a predetermined person identified by the communication device running the digital image processing method as the user. The user may, for example, be understood to be the owner of the communication device.

The identification information identifying the person corresponding to the recognized face depicted in the digital image may identity the person according to the person's name, a network account corresponding to the person, a nickname corresponding to the person, or a code name corresponding to the person. The relationship information may describe a relationship between the person and the user such as, for example, a family relationship, a kinship, a schoolmate relationship, a colleague relationship, a friend relationship, or the like.

At S13, digital image information of the digital image is acquired. The digital image information may include at least one of a digital image capturing time and a digital image capturing location of the digital image.

The digital image information of the digital image may be extracted from an exchangeable image file (abbreviated as exif) corresponding to the digital image. The exif may include metadata that is assigned to digital images captured by a digital camera, where the metadata includes at least one or more of the following types of information upon capturing the digital image: a digital image capturing time, digital image capturing equipment (e.g., main body of the equipment, lens, flashlight, etc.), digital image capturing parameters (e.g., shutter speed, aperture F-number, ISO speed, focal length, metering mode, etc.), image processing parameters (e.g., sharpness, contrast, saturation, white balance, etc.), image description and copyright information, a digital image capturing location (e.g., GPS positioning data, etc.), and a thumbnail of the digital image.

At S14, a description of the digital image may be generated according to the identity information and the digital image information. For instance, identity information of faces depicted in the digital image may be obtained by image recognition techniques that recognize face(s) depicted in the digital image. Then based on the obtained identity information, it may be determined that the person corresponding to the recognized faces depicted in the digital image are those of the user's parents. The digital image information may describe attributes of the digital image itself such as a time/date when the digital image was captured and a location where the image was captured. For example, the acquired digital image information of the digital image may include a digital image capturing time of Oct. 1, 2015 and a digital image capturing location of Tiananmen in China.

Then, by analyzing the digital image and obtaining the identity information and/or the digital image information, the following information may be obtained: “parents” for relationship information, “Oct. 1, 2015” for digital image capturing information, and “Tiananmen, China” for digital image capturing location information. Then, a description of the digital image (e.g., “with parents at Tiananmen on Oct. 1, 2015”, “have a trip in Beijing with parents on Oct. 1, 2015”, etc.) may be generated by using an abstract generation technology among natural language processing technologies (e.g., Extractive algorithm or Abstractive algorithm).

In this embodiment, the face(s) depicted in the digital image maybe recognized and the description of the digital image may be generated according to the identify information of the person corresponding to the recognized face(s), as well as the digital image information of the digital image, so that the description of the digital image may be generated more accurately. The intelligence for automatically generating a description of a digital image is improved to be closer to a human's ability to describe the digital image, and thus the user may quickly obtain an accurate description of every digital image, and the user experience is improved.

In another embodiment, the identity information for the person corresponding to the recognized face may be determined according to one of the following implementations.

I. According to a first implementation, identity information of the person corresponding to the face depicted in a digital image may be determined according to a preset personal information database.

FIG. 2 is a flow chart 200 describing a digital image processing method for determining identity information of a person corresponding to a face depicted in a digital image according to a preset personal information database according to another exemplary embodiment. The digital image processing method may be implemented by a communication device.

At S21, a personal information database may be acquired from a data storage device, where the personal information database includes correspondence relationships that match up facial recognition information with corresponding identity information. The personal information database may be predetermined and stored on the data storage device prior to the implementation of the digital image processing method described by flow chart 200. For example, the personal information database may be in a prepopulated table data format.

At S22, the recognized face may be compared with the facial recognition information in the personal information database to identify facial recognition information in the personal information database which matches the recognized face.

At S23, identity information corresponding to the facial recognition identified in the personal information database as matching the recognized face is acquired.

The user may pre-store the information included in the personal information database in advance. For example, the personal information database may be generated by inputting face photos of family members into the personal information database and setting identity information for the face photos that identify the family member's identity. The personal information database may also be generated by assigning a family relationship type of relationship information corresponding to a face photo or identity information already stored in the personal information database. This may be done for every family member identified for the user. Additionally or alternatively, schoolmates, friends, colleagues or other relationship information may be added to the personal information database.

II. According to a second implementation, identity information of the person corresponding to the face depicted in a digital image may be determined according to contact information of the user.

FIG. 3 is a flow chart 300 illustrating a digital image processing method for determining identity information of the person corresponding to the face depicted in a digital image according to contact information of the user according to another exemplary embodiment. The digital image processing method may be implemented by a communication device.

At S31, contact information corresponding to the user may be acquired. The contact information may be a contact list stored on a memory of the communication device implementing the digital image processing method. The contact information may include head portrait digital images that include a person's face and identity information of contacts known by the user (e.g., people whose contact information is included in the contact list).

At S32, the recognized face may be compared with the head portrait digital images included in the contact information to identify a head portrait digital image which matches the recognized face. In particular, people's faces depicted in the head portrait digital image may be parsed and analyzed to identify a head portrait that includes a person's face that matches the recognized face.

At S33, identity information corresponding to the head portrait digital image that includes the people's face that matches the recognized face is acquired.

Thus, the identity information of the person corresponding to the recognized face in the digital image may be determined according to the head portraits in the contact list.

In this embodiment, these two implementations for determining the identity information may be utilized alone or in combined together, which is to say, the identity information may be determined according to one, or both the personal information database and the contact information in the contact list.

In this embodiment, by determining the identity information for the person corresponding to the recognized face according to either of the above-described implementations or a combination thereof, the identity information for the person who's face is depicted in the digital image may be determined precisely, so that a more accurate description of the digital image may be generated subsequently according to the determined identity information, the intelligence for automatic description of a digital image is improved to be closer to a human's ability to describe the digital image, and the user can quickly obtain an accurate description of a digital image, and user experience is improved.

In another embodiment, to generate the description of the digital image more accurately, other information of the digital image (e.g., digital image information, information of an object other than faces in the digital image, or the like) may be further acquired.

FIG. 4 is a flow chart 400 describing a digital image processing method according to another exemplary embodiment. As shown in FIG. 4, generating the description of the digital image may further comprise the following steps in addition to the steps described by flow chart 100. The digital image processing method may be implemented by a communication device

At S41, an object depicted in the digital image may be recognized, and a name identifying the recognized object may be obtained.

Image recognition algorithms such as region based convolutional neural network (R-CNN) and fast convolutional neural network (fast-CNN) may be utilized to recognize object(s) contained in a digital image. For example, possible candidate areas are first framed in the digital image, and then CNN classification is performed for objects in the framed areas.

At S42, the description of the digital image may be generated according to one or more of the identity information, the digital image information, and the name of the object.

For example, when the digital image capturing time of the digital image is determined to be Oct. 1, 2015, the digital image capturing location of the digital image is determined to be Tiananmen Square, the relationship information identifies the faces in the digital image to be those of the user's parents, and the names of the recognized objects in the digital image identify the objects as flowers, a national flag and the like, then the generated description may be “see a flag-raising ceremony with parents at Tiananmen Square on Oct. 1, 2015”.

Furthermore, in addition to the identity information, the digital image information and the name of the object, other information may also be taken into consideration to automatically generate the description of the digital image (e.g., weather information for the day on which the digital image is taken, a news event occurring at the digital image capturing time and location, or the like.)

In this embodiment, the description may be generated according to various types of information related to the digital image, so that the description becomes more accurate, the intelligence for automatic description of a digital image is improved to be closer to human's ability to describe the digital image, the user can quickly get an accurate knowledge of every digital image, and user experience is improved.

In another embodiment, digital images may be grouped into a collection of digital images, and an overall description may be generated for each collection of digital images. FIG. 5 is a flow chart 500 illustrating a digital image processing method according to this exemplary embodiment.

At S51, digital images may be grouped into a collection of digital images. The digital images that are grouped may correspond to the user in some way. For example, each digital image may include a depiction of the user among other digital image content.

In step S52, a description of each collection of digital images may be generated according to a description of each digital image in the collection of digital images.

For example, representative text fragments may be extracted from descriptions corresponding to individual digital images in each collection of digital images by employing the Extractive algorithm. The representative text fragments may then be integrated to generate the description of each collection of digital images.

The digital images may be grouped according to digital image capturing scenes. Grouping the digital images into a collection of digital images may include grouping the digital images according to at least one of the following factors: digital image capturing times and digital image capturing locations of the digital images and faces in the digital images.

For example, the user may group the photos taken on Oct. 1, 2015 into one collection of digital images, group the digital images taken at Tiananmen Square into another collection of digital images, all the digital images containing the faces of the user's parents into another collection of digital images, the digital images taken at Tiananmen Square on Oct. 1, 2015 into another collection of digital images, the digital images containing the faces of the user's parents and taken on Oct. 1, 2015 into another collection of digital images, the digital images containing the faces of the user's parents and taken at Tiananmen Square into another collection of digital images, or the digital images containing the faces of the user's parents and taken at Tiananmen Square on Oct. 1, 2015 into another collection of digital images.

Digital images taken in the same scene may be assigned to different collections of digital images by grouping these photos based on information such as digital image information of the digital images and faces in the digital images, thereby facilitating subsequent accurate automatic description of each collection of digital images.

The user may access and browse the digital images according to collections of digital images, where the grouping and the description of each collections of digital images may be displayed upon reception of a browsing command input by the user to the communication device with control over access to the collections of digital images. In addition, the digital images in each collection of digital images and the descriptions of the digital images may be displayed in a slideshow manner.

In this embodiment, the digital images may be described according to the collection of digital images to which they are assigned to, and the grouped digital images and the description thereof may be displayed, so that the user can quickly get an accurate knowledge of each group of digital images and user experience is improved.

The relationship information may describe a relationship between the person and the user such as, for example, a family relationship, a kinship, a schoolmate relationship, a colleague relationship, a friend relationship, or the like.

An acquiring module 63 may be configured to acquire digital image information of the digital image, the digital image information comprising at least one of a digital image capturing time and a digital image capturing location of the digital image.

The digital image information of the digital image may be extracted from an exchangeable image file (abbreviated as exif) corresponding to the digital image. The exif may include metadata that is assigned to digital images captured by a digital camera, where the metadata includes at least one or more of the following types of information upon capturing the digital image: a digital image capturing time, digital image capturing equipment (e.g., main body of the equipment, lens, flashlight, etc.), digital image capturing parameters (e.g., shutter speed, aperture F-number, ISO speed, focal length, metering mode, etc.), image processing parameters (e.g., sharpness, contrast, saturation, white balance, etc.), image description and copyright information, a digital image capturing location (e.g., GPS positioning data, etc.), and a thumbnail of the digital image.

A first generating module 64 may be configured to generate a description of the digital image according to the identity information determined by the determining module 62 and the digital image information acquired by the acquiring module 63.

Then the first generating module 64 may use an abstract generation technology among natural language processing technologies to generate a description of the digital image as follows: “with parents at Tiananmen on Oct. 1, 2015”, “have a trip in Beijing with parents on Oct. 1, 2015”.

In this embodiment, the face(s) in the digital image may be recognized by the recognizing module 61, and the first generating module 64 generates the description of the digital image according to the identity information corresponding to the face(s) determined by the determining module 62 as well as the digital image information of the digital image acquired by the acquiring module 63, so that a description of the digital image may be generated more accurately, the intelligence for automatic description of a digital image is improved to be closer to human's ability to describe the digital image, the user can quickly get an accurate knowledge of every digital image, and user experience is improved.
